Biosorption Of Colour In Landfill Leachate Using Acid Pre-Treated Hydrilla Verticillata

Leachate from landfills is a complex fluid with a wide range of amounts and structures in fluid content, chemical composition, and others. It also contains high amounts of biodegradable and nonbiodegradable compounds such as organic matter, phenols, ammoniacal nitrogen, phosphate, heavy metals, and...
